ROTARY TOOL

PROBLEM TO BE SOLVED: To provide a rotary tool that prevents the deformation of a control circuit board by following the deformation of a housing even if the housing is deformed by a large load such as drop impact while allowing the control circuit board to be arranged at a part distant from a part directly hitting a floor even if dropped at a state of installing a battery pack. SOLUTION: The rotary tool is provided with a grip 3 to be gripped by hand on a housing 2 of a rotary tool body 1, and a battery pack 4 attachably/detachably installed at one end of the grip 3. A control circuit board arranging part 6 is provided in order to arrange the control circuit board 7 on the side, where the battery pack 4 is attachably/detachably installed, at one end of the grip 3. The housing 2 is composed by fittingly attaching right and left two-divided housing halves 2a. A fitting groove 24 is provided in the internal surface in the lateral direction of each of the two-divided housing halves 2a. An elastic body 8 is mounted so as to be along the edge of the control circuit board 7. The elastic body 8 is fitted into both fitting grooves 24, thereby holding the control circuit board 7 to the housing 2 via the elastic body 8. COPYRIGHT: (C)2010,JPO&INPIT
